I have had friends show me really bad videos of people being brutally tortured and being killed. They freaked out by the videos but i can just stare at the screen and it doesn't bother me at all. I like watching it for some reason. There was one time where my friend showed me the video three guys one hammer and he told me to turn it off. I said "no, you told me to watch this video and I am going to watch the whole thing." Is this normal?
